OVERVIEW

Premium Performance for Automated Welding

Upgrade your welding operations with the NS ER70S-6 .035" Copper-Free MIG Wire, delivered on a substantial 1000 lb wooden reel. This wire is designed for the professional welder and fabricator who demands consistency, feedability, and superior arc characteristics. The "Copper-Free" (CF) technology is a game-changer for long-conduit runs and push-pull systems often found in automated setups. Without the layer of copper found on traditional wires, you eliminate the risk of copper shavings accumulating in your liner, which is a leading cause of erratic feeding and arc instability.

The ER70S-6 formulation provides the highest combination of manganese and silicon deoxidizers available in a standard mild steel MIG wire. This allows for higher welding currents with CO2 shielding gas and improved puddle fluidity with Argon/CO2 mixtures. The result is a smooth, spatter-free weld deposit that ties in nicely at the toes, even when welding on hot-rolled steel with scale or minor surface contaminants.

This 1000 lb reel format is intended for use with heavy-duty payoff equipment or dereelers. It is the ideal solution for shops running continuous shifts where stopping to change a 33lb or 44lb spool interrupts the workflow. Whether you are welding automotive components, structural steel, or heavy machinery, this NS wire delivers the reliability required for critical welds.

Technical Advantages

  • Superior Feedability: Precision winding and consistent cast/helix ensure the wire feeds smoothly without wandering.
  • Extended Consumable Life: Cleaner wire surface reduces wear on contact tips and liners.
  • Versatile Shielding Gas: Performs exceptionally well with 100% CO2 or 75/25 Argon/CO2 mixes.

FAQ

Copper-free wire eliminates copper flaking, which can clog liners and contact tips. This results in smoother feeding, a more stable arc, and reduced maintenance downtime, especially in long conduit runs.

You will need a heavy-duty wire payoff system, dereeler, or turntable capable of supporting a 1000 lb wooden reel and providing proper tension control to prevent tangling.

This wire can be used with 100% CO2 for deep penetration or an Argon/CO2 blend (typically 75/25 or 90/10) for a smoother arc and reduced spatter.

Yes, the ER70S-6 classification contains high levels of silicon and manganese deoxidizers, making it capable of handling light to moderate rust and mill scale.

This wire has a diameter of 0.035 inches (0.9 mm), making it versatile for welding thin to medium-thickness materials.

NS copper-free wire is treated with a proprietary surface lubricant and rust inhibitor to prevent corrosion during storage, offering shelf life comparable to copper-coated wires when stored correctly.

Absolutely. The 1000 lb bulk packaging and copper-free finish are specifically optimized for robotic applications to maximize uptime and consistency.
